doesn't explicitly say anything about progressive DCT compressioin,
but the compression isn't supported nor by Adobe nor Aladdin gs.
So it needs either data re-encoding or at least warning message.
FYI, gs supports progressive JPEG if compiled with progressive-enabled libjpeg. That is not the default build but it only takes a one-line change to a config file to make it happen.
You are right that Adobe RIPs do not cope with p-JPEG, so it would probably be better if tiff2ps re-encoded progressive data to non progressive...
